Vulnerabilities: Improper Input Validation, Information Exposure Through Log Files, Improper Privilege Management
Successful exploitation of these vulnerabilities could cause information disclosure of device logs, denial of service through device reboots of the patient monitors, and privilege escalation.
The following versions of Dräger patient monitoring medical devices are affected:
3.2.1 IMPROPER INPUT VALIDATION CWE-20
A malformed network packet may cause the monitor to reboot. By repeatedly sending the malformed network packet, an attacker may be able to disrupt patient monitoring by causing the monitor to repeatedly reboot until it falls back to default configuration and loses network connectivity.
CVE-2018-19010 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
3.2.2 INFORMATION EXPOSURE THROUGH LOG FILES CWE-532
Log files are accessible over an unauthenticated network connection. By accessing the log files, an attacker is able to gain insights about internals of the patient monitor, the location of the monitor, and wired network configuration.
CVE-2018-19014 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
3.2.3 IMPROPER PRIVILEGE MANAGEMENT CWE-269
Via a specific dialog it is possible to break out of the kiosk mode and reach the underlying operating system. By breaking out of the kiosk mode, an attacker is able to take control of the operating system.
CVE-2018-19012 has been assigned to this vulnerability. A CVSS v3 base score of 8.4 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
